The York Radio Club website is chock-full of current info about emergency sirens, radio frequencies, and other amateur radio topics. Here’s what they have to say about themselves:
Incorporated in 1936
York Radio Club was incorporated in 1936 under the laws of the State of Illinois. In 1938 we affiliated with the American Radio Relay League and we have maintained that affiliation ever since.
An A.R.R.L. Special Service Club
For a number of years now, York Radio Club has maintained its status as a Special Service Club within the ARRL.
According to the ARRL, “A special program exists to recognize those ARRL Affiliated clubs who do more than the usual for their communities and for Amateur Radio. These well-rounded groups are the Special Service Clubs (SSCs). SSCs are the leaders in their Amateur Radio communities. They’re the ones with the active training classes, the publicity program and the members who actively pursue technical projects and operating activities.
Truly special Amateur Radio clubs are well balanced in their programs for serving the community, developing club members’ Amateur Radio skills and social activities, striving each year to build on their successes to improve their effectiveness. The objective of the ARRL’s SSC program is to help good clubs organize and focus their efforts on those things that really count. Being an SSC should mean that members have certain skills, that the club as a group has the ability to improve service inside and outside the Amateur Radio community, and that it does so when needed.”
There’s lots more on their website, including lots of ham radio lingo that I don’t understand.
